A lengthy post on Rusted Logic has interesting details from a user who has done extensive work to restore content to Fallout New Vegas that was cut by Obsidian during development of the action/RPG sequel. His mods to do so can be found here. The post was first written a couple of weeks ago, offering extensive details on cut content, though it was recently edited it to add a clarification that this is not intended as criticism of the developer. Thanks Acleacius.
